Honeywell's LT refrigerant receives ASHRAE designation
[firstParagraph]
HONEYWELL'S R22 replacement for commercial supermarket refrigeration, Genetron Performax LT, has received the official ASHRAE designation of R407F.
A blend of R32, R125 and R134a, it is preferred at low temperatures to R407A due to its higher capacity. It also has the lowest GWP of all commonly used blends, including R404A and R407A
This refrigerant has a A1 safety classification, being non toxic and non flammable.
R407F is designed to be used in both new equipment and as a retrofit in equipment that uses R22. It is said to provide similar performance to R22, but requires fewer equipment modifications than other R22 retrofit alternatives.
